A complaint from the ACLU Foundation of San Diego and Imperial Counties and ACLU Border Rights Center, based on interviews conducted in San Diego and Tijuana, found “a number of troubling cases in which CBP processing and/or detention led to family separations, including:”
* A woman whose heart condition worsened when, during processing, the Border Patrol separated her and her sister and transferred her sister to a different detention center without any advance notice or opportunity to say goodbye;
* A mother and her two sons (one a minor) apprehended by the Border Patrol and detained in a nearby station; when the mother, who had seriously injured her knee during her journey to the United States, was taken to a hospital for surgery, she was separated from her boys, who were left detained separately at the Border Patrol station. After her return from the hospital, the Border Patrol released the mother and minor son into the United States together, but separated the older son from them and transferred him to U.S. Immigration and Customs Enforcement (“ICE”) detention; 
* A grandmother who Border Patrol agents separated from her nine-year-old grandson after agents told her that his birth certificate was insufficient to establish biological familial ties. The grandmother was left anguished and fearful that her grandson would be given up to a U.S. family for adoption; and
* A family of nine which CBP separated into three different family units—notwithstanding the fact that all nine family members initially entered the United States together—and subjected to the so-called “Migrant Protection Protocols.” The entire family was forcibly removed to Mexico, with each of the three “units” then receiving different master calendar hearing dates. This, in turn, resulted in separate nonrefoulement interviews. The stress of this arbitrary and inefficient separation of family members led the mother in the family to experience hyperventilating, vomiting, headache, and chest pain while awaiting her own nonrefoulement interview.

Footnote from above:
: This family also included a father and two additional minor children, who had been separated from the mother and sons while crossing into the United States. Although the father saw one of his sons through a glass window while detained at the Border Patrol station and tried to explain to agents that his wife and other children were on site, the Border Patrol made no effort to reunite the family, and did not tell the mother that her partner was detained at the same station.
